Default Camera problem: red/blue/purple noise in low light photos

Same story from M7 continues with M8. Taking pictures in low light has red/blue/purple noise/tint.
Here is video sample:

HTC ONE M8 Camera Issue- Pink/Red Tint like M7: http://youtu.be/b2sdyGi7-NA

Here's screenshot:


You can clearly see on video and picture heat shielding starts degrading, thus parts of the heat transfers to sensor.

Mine M8 produced in May 2014, serial number HT45.
Sensor is Omnivision OV4688 4M.
You can check sensor via file manager, no root is required.
For example, in Solid explorer:
Choose System Root - Sys - android_camera - sensor - open as - Text file - SE TextEditor.

Please report if you anyone has such issue.

I do not have this Problem.
So, idk why people should not buy HTC phones.

As if any other Phone is perfectly without any known issues
And no, having a definately Defect unit/device does NOT count as comparison or example.


Use your warranty, and let it repair / get exchanged for another device --> problem solved.
No magic unicorn will appear and fix it. Your camera sensor is defect, nothing more, nothing less. Thats what warranty is for.

Don't have this issue here and my phone gets HOT. This is also why we have warranties and insurance. Non htc phones break when dropped, run like crap, or have other issues like built like a mcdonalds toy.

This thread is a non issue in my book.

No issue here. If the M8 would have the same issue as the M7 did we would have heard of it by now from many more users. You just have bad luck I guess and got a bad unit.

It only happens when it's using an ISO of 3200.
When I set the ISO manually, even at 1600 there is no trace if it.

This is a "issue" with GAIN. If you take ANY sensor and maximise the gain (ISO) you will get more noise and these artefacts.

Even my DSL has the same problem with 12800 iso and total black. There will be dots and stuff all over the image. Especially with noise reduction on low or even dissabled.

ISO is just a mather of removing more or less noise from the sensory data. Consider it a radio, maximising the volume will make it hum and other things, stuff that you wont notice with sensible volume/gain. Nothing is free of noise and camera sensors are analog and take in noise and IR-radiation esp if the phone is warm. You can prevent this noise appearing but then you get worse performance in Low SNR (signal-to-noise ratio) situation - like dark images.
